The mount is an interesting concept. It either has to be an adapter or some sort of collar that extends out.
If it's true, it will be a great way to get some decent zooms other than shelling out for the Panasonic 2.8s. Not to mention, phase AF is going to be huge if it works well.
My only complaint on the EM-5 is that I would like a mic input. 3.5mm would be just fine. There really is no excuse not to add one, and if you want anyone to take your video at least halfway serious, you should have one. The hotshoe mount just doesn't work.
They probably will have a better adapter, though they are coming out with 2.8 zooms like panasonic, though not the 2.0's of FT size. The only problem of the original FT lenses is they are not that small, in fact they're pretty big in comparison to the body, though the oly lenses like the 200 f2 are fine optics and build.
Having both the gh3 and the omd, I can tell you the gh3 is a much better video camera, actually much better camera overall, the omd feels better, shoots a 10% better still file and is more endearing and that last word is hard to say because the omd is also maddening.
The menu is insane. It's like 14 main items with 86 sub menus, or something crazy. I spent 45minutes a night, when time permitted, for two weeks, went through 14 or so websites just to find out how to set wysiwyg in the ovf.
I did it and set it on a special myset function and still don't don't what the combination is to do it, I just know I did it.
So is the no output for 3.5 mm headphone jacks. Makes no sense, on any camera that shoots video, even if you run to a separate recorder.
The OMD video thing is just goofy because the i.s. in the body is so very good. Why they don't match panasonic in video function has to be some kind of back door handshake deal with Sony that nobody can make sense of it.
With all it's issues and as crazy as the omd is to work at times, it feels like a jewel, well like a leica and one of the few cameras that you throw over your shoulder and everyone says, "wow" that's a beautiful camera.
I personally love working with micro 4/3's for lifestyle advertising. The cameras are just perfect in size, you can throw two or three on your shoulder, go to video in an instant, (good video . . . real good video) and then flick a switch and if you know how to process well, you can produce a great still.
I also like the idea of a blackmagic 4/3's camera for a 16mm look, as long as it works. I've gone through some of the teething pains of the RED and can't do it again in production, so if the small blackmagic 4/3's works I'll be there.
I find both the gh3 and the omd to shoot a very strange but pretty file. It seems that no matter what you do they come out kind of green, almost identical to RED One files (so it's something I'm use to), but with some correction they look what I consider film like and a lot of people have a different view on what film like is. Some think it's the smoothness of a 5dIII but to me film like is kind of grainy, kind of textured and looks like well . . . film and that's what I see when I use the OMD.
The only thing needed is for Olympus to wake up. I know the Iphone has killed the market for small cameras, but the pen series, the omd are stunning cameras in look and feel, but they need more function, a little better higher iso . . . not a lot a little and some logic with the menu.
Olympus needs more consistency in their mft lenses. Some like the 75mm rival lecia in build quality some look good, but feel like plastic and very light, though all the oly lenses are amazing sharp actually as sharp as my zeiss contax where are the sharpest real world lenses I've ever used. Much sharper than my leica lenses.
Actually, in the world of digital I think sensor size matters less than usability. At least in what I do. I like these smaller cameras, because regular dslrs are huge. It's not a life or weight issue, it's just dslrs all look the same (black) and all look like plastic and a camera like the omd is different and a joy to hold and use. Maybe the new blackmagic will be the same. I hope so, but I really wish I could pick and choose the video capabilities of the gh3, the file quality (hopefully) of the black magic, the file codec (prorezz) of the black magic and the look, feel and build of the OMD.
But........ the omd menu is truly painful.
